When I have the engine on running you can smell antifreeze from the engine..but there is no sign of leaks at any possible place visible. But the overflow coolant tank gets low by about a inch or so every couple of weeks? A guy told me it could be leaking in the fire wall going to the heater core in the glovebox?

When replacing the seals alongside the ring carrier bearings I ran into a soft RTV type next to the seals and cannot find them in the parts book yet they look like factory made seals. Do I leave them out or add RTV from a tube? I am a 'heavy' truck mechanic for over 45 years and have never seen seals installed this way. Thanks for your help!

on my husbands 2002 dodge 1 ton diesel the engine turns over several severl times before the truck will start, but it always starts. We found on the internet how to re-calibrate the tps/apps and tried that, it helped somewhat, the truck doesn't have to turn over as many times before starting now, but more than it should. This is something that happens everytime he starts the truck. Also there is no loss of power during acceleration, which makes me think it may not be the tps/apps. please advise...thank you
